lApplication led April 6, 1916. Serial No. 89,291.

To ZZ clio/izI it may Concern.'

Be it l-:nown that I, CHARLES L. Bas'riAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois` have invented certain new and use- 't'ul Improvements in Soda-Fountain Apparatas. of which the following is a specification.

This invention relates to soda fountains and .its object is, broadly, to improve the arrangement of the syrup jars with relation to the counter so that they will be accessible for obtaining` syrup therefrom as required and at all times will be protected from wash or waste water or drippings from the counter.

Another' object of the invention is to arrange the jars and the pump mechanism thereof so that they can be readily removed from the counter for cleansing and also to secure the ars in place in the counter by reason of the engagement of the pump mechanism with the. counter.

A further object of the invention is to provide a pump mechanism operated by air pressure which may be obtained from the top of the tank of the carbonating machine or any other source of supply to provide a quick-acting pump for insuring a complete charge of syrup at each operation.

Other objects will ap ear hereafter in the detail description of tlie invention in the embodiments thereof illustrated in the accompanying drawings, in which- Figure 1 is a sectional view on the line 1 1 of Fig. 2, showing my invention in its preferred form in place in the counter Vin full lines` and pulled out from the counter in broken lines so that the pump mechanism may be removed from the jar;

Fig. 2 is a plan view of a portion of a counter with the top thereof removed;

Fig. 3 is an enlarged horizontal sectional view showing the. pump mechanism as illustrated in Figs. l and 2;

Fig. 4 is a sectional view on the line 4 4V of Fig. 5 showing my invention embodied in a tilted syrup jar;

Fig. 5 is a plan view, partly in section, of the syrup jar illustrated in Fig. 4;

Fig. 6 -is an enlarged sectional view of the pump mechanism illustrated in Fig. 4 but mounted underneath the plate;

Fig.V 7 is a view, partly in section, illustrating' diagrammatically the relative arrangement of a soda fountain counter and a.

. carbonating machine with my invention embodied therewith;

Fig. S is a detail fragmentary View. Referring to the drawings and first more particularly to Figs. 1-3, 8 designates generally a counter which maybe made of any suitable construction having a top 9 under which there is provided a plurality of compartments 10 to receive the syrup jars 11.

Each syrup jar has a recess or Well 12 in its bottoni at the front thereof and the bottom of the compartment is providedwith a raised portion 13 to support the jar. At the front of the compartment there is a hinged door 14 which may be opened to permit the insertion and removal of the syrup jar and l is preferably made as a single unit having all the parts thereof connected together so that it can be removed from the jar as a whole. This mechanism comprises a top plate 19 which is arranged to slide in guides 20 on the sides of the compartment to support the mechanism in Xed position within the jar. A face plate 21 rigid with the plate 19 closes the opening at the front of the compartment above the door 14. A pressure chamber 22 is mounted in the plate 19 and a piston rod 23, operating through the bottom of said chamber, carries a plston 24 at its upper end within the chamber and a plunger 25 at its lower end to operate in a charge chamber 26. This charge chamber is arranged in the recess or Well inthe jar and is provided with a valve 27 in its bottom and with a guide 28 engaging a notch in the plunger 25 to guide the latter in its movement in the charge chamber. A spring 29 arranged between the bottom of the pressure chamber and the piston therein nor-l mally holds the piston and plunger in elevated position, as shown in Fig. 1. A dis- -char e pipe 30 isconnected to and connects the c arge chamber 26 with the plate 19 and -is provided with a discharge spout 31 which' through ports 34 in one end 35 thereof with receive a nozzle 16.

an inlet chamber 36 and within this chamber there is arranged a rubber socket 37 to The spring-pressed valve 17 normally closes this nozzle but when the pumpmechanism is arranged in place the socket 37 is forced on the nozzle to make a tight connection and the end 35 of the valve chamber engages the stem 18 and unseats the valve 17 to permit pressure from the pipe 15 to enter the chambers 36 and 32 (Fig. 3). A piston rod 38 is arranged to operate through the other end of the valve chamber and through the face plate 21, being provided with a knob 39 on its outer end for convenience in operation.

This rod carries two pistons 40 and 41 and the valve chamber is provided with a by* pass 42 and an exhaust port 43.

In normal position the valve 17 Vis unseated and the pistons and 41 are projected forward, as shown in Fig. 3, by the pressure behind the piston 40. When it is desired to obtain a charge of syrup the piston rod 38 is pushed inward until piston 41 shuts ofi' the exhaust port 43 and piston 40 is positioned with reference to the by-pass 42 to permit pressure to pass through the chamber 32 between the pistons and throu h port 33 into pressure chamber' 22 above tIie piston 24 therein. The piston 24 is pressed downward against the spring 29 and the plunger 25 forces the syrup out of the charge chamber 26 through pipe 30 and discharge.

spout 31. When the knob 39 is released the pressure behind pistons 40 and 41 will force them to forward position permitting the pressure between the pistons and in the pressure chamber to escape through the eX- haust port 43, whereupon the spring 29 will return the piston 24 and plunger 25 to normal position. The action of the parts will be quick and cause the charge of syrup to flow from the spout 31 in a steady stream. The charge chamber automatically refills because it is located at the lowest point in the syrup jar.

In this construction, (Figs. 1-3) the syrup jar is entirely covered by the' top of the counter, as shown in Fig. 1, the only eX- posed parts thereof being the knob 39 and the nozzle 31 so that the jar is entirely protected against waste water and washing water flowing or dripping from the counter. This I consider a very important feature of my invention since it is highly desirable to maintain the syrup jars in a clean and wholesome condition and the contents thereof free from contamination and also because waste or washing water or drippings from the counter. are liable to enter the jars i permitted to flow over any part thereof as has been customary to a verylarge extent heretofore.

To remove the jar for cleaning or to refill the samev or for any other purpose, the door 14 is opened and the pump mechanism is pulled outward with the jar until the plate 19 is free from the guides 20, (shown in broken lines in Fig. 1) whereupon the pump mechanism may be removed from the jar. By the time the socket 37 is disengaged from the nozzle 16 the valve 17 has seated to prevent the escape of pressure from the nozzle.

In Figs. 4-5, I have shown my invention embodied in a familiar form of tilted in a counter 44 having a comparatively narrow top 4 5.U The jar 46, lwhich may be made of any suitable material, is supported in an inclined position and the pump mechanismy (which corresponds in all substantial respects` with that heretofore described and is designated generally 47 to avoid further detail description) is mounted in the plate 48, the upper edge of which is arranged to fit snugly against the rear edge of the counter to form a close joint therewith. In the construction of Fig. 6 the pump mechanism there designated generally 49 is mounted on the underside of the plate 50 which is intended to abut snugly against the rear edge of the counter' in substantially the manner illustrated in Fig. 4. In the construction of Fig. 4 and Fig. 5 the valve chamber 51 is connected by a pipe 52 with the inlet chamber'53, which pipe enters the valve chamber above its bottom and serves the same purpose as the by-pass in the construction of Figs. l1-3. While I prefer the construction of Figs. 1-3 it will lbe observed that in the construction of Figs. 4-6 the syrup jar is also, to a very considera-ble extent, protected against waste or washing water or drippings entering the jar. In the latter constructions the pump mechanism is wholly protected and the jar is completely covered by the plate, the only openings therein being those provided for the piston rod 54 and the nozzle 55.

I may obtain air or gas pressure for operating the pump from any suitable source of supply. I may take this pressure from the top of the tank 56 of the carbonating machine by connecting the pipe 15 therewith, as shown in Fig. 7 This pipe should be provided with a. valve 57 so that pressure may be shut off entirely from the syrup jars and also with a reducing valve 58 to reduce the pressure as desired. By this means I not only obtain pressure for the operation of the syrup pumps by means constituting a part of a soda fountain apparatus but also remove the air which accumulates in the top of the carbonating tank andavoid the necessity for snifting.

-'My invention provides a soda ,fountain apparatus 0f simple construction in which the syrupA jars are wholly protected from 'water or dri pings from the top of the counter entering the jars and enables them to be kept in a sanitary condition, at the same time providing a compact arrangement of parts with a wide top for the counter completely covering the jars in the preferred form of the invention. `With the exception of the charge chamber plunger the operative parts ofthe pump mechanism are entirely .protected from contact with the syrup and this enables lthe pump mechanism to be easily cleaned.4 The pump mechanism is engaged with the sides of the compartments when arranged in place in the jar and this arrangement keeps the jar in place in its com artment wholly inclosed with the eX- ception of the knob for operating the pump;

pistons and the discharge end of the nozzle, both of which are conveniently located for use. By taking the pressure from the top of the carbonating tank the cost of maintenance is reduced to a minimum and the necessity for snifting the machine to let out the air which accumulates in the top of 'theV tank is avoided. v

I am aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and scope of my invention or sacrificing any of the advantages thereof and I therefore reserve the right to make all such changes as fairly fall within the scope of the following claims.
